The skeletal frames surrounding buildings as they grow in height are such a common site in New York City, most people may not give scaffolding a second glance. In fact, according to the U.S. Occupational Safety and Health Administration, this framework is a part of the job for 65 percent of construction workers in the United States. OSHA has developed standards, but estimates that non-compliance is an ongoing issue that leads to about 60 deaths and 4,500 injuries each year.

One common theme of OSHA’s safety standards for every aspect of scaffolding is the requirement to be strong enough to exceed the intended load. For example, a metal tubular frame scaffold must be able to hold a load four times heavier than the maximum load it is intended to support, and all the hardware connecting the frame, such as the legs, brackets and braces, must have the same weight load capability. In spite of the added capacity, no part of the structure should be used in excess of the intended weight.

In addition to the quality of the materials, the specific construction of the scaffolding is outlined by OSHA guidelines, as well. This includes the placement of planks on supports, the way the legs are placed and braced, and the height and placement of guardrails, to name a few.

Not only does OSHA have strict standards for the structures themselves, the safety requirements also provide extensive details about the conduct of those who are using them. People working on scaffolds who have not received adequate training put themselves and everyone around them in danger. OSHA places responsibility on construction companies because following the guidelines to the letter is the only way to ensure that workers are not injured or killed on the job.
